Activities and their intensity.

I listed the following activities for you to have an idea of the comparative intensity of different activities. The activities are listed in descending order by intensity measured in METs. One MET is equal to a person's oxygen uptake at rest. So you will use 4 times as much oxygen as you consume at rest in an activity that is rated at 4 METs. Take a look at the list.
